You would wana use SA=2lw+2lh+2hw
so SA=2(8×2)+2(8×12)+2(2×12)
make the calculations than mention how you find the surface of one side of the box than the whole surface area by using that formula
Answer:
2x+12
Step-by-step explanation:
2x+3(x−2)−3(x−6)
Distribute:
=2x+(3)(x)+(3)(−2)+(−3)(x)+(−3)(−6)
=2x+3x+−6+−3x+18
Combine Like Terms:
=2x+3x+−6+−3x+18
=(2x+3x+−3x)+(−6+18)
=2x+12
Answer:
=2x+12
